hi there, I am attempting to compile bitcoin code on OSX Sierra 10.12.1, and get this error:

AR       leveldb/libmemenv.a
  CXXLD    bitcoind
Undefined symbols for architecture x86_64:
  "Db::verify(char const*, char const*, std::basic_ostream<char, std::char_traits<char> >*, unsigned int)", referenced from:
      CDBEnv::Verify(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, bool (*)(CDBEnv&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)) in libbitcoin_wallet.a(libbitcoin_wallet_a-db.o)

Any pointers into resolving this? Apologies if this is not the correct forum.
